Carrier-based WiFi calling uses IPSec and bypasses whichever VPN installed on phone, but what if the router itself is set to use OpenVPN or WireGuard? Would IPSec WiFi Calling go through router's OpenVPN/WireGuard tunnel without issues?
Thanks, I've already seen some of those threads, but I couldn't find anything specific in regards to IPSec WiFi calling running inside OpenVPN or WireGuard tunnel established by router. SIP and IPSec WiFi calling don't use the same protocols.

Just a datapoint: I use IPSEC wifi calling on my iPhone XS (iOS 16.0.2) every day over my router (WRT1900ACSv2, on build 49081) with no issues that I'm aware of. Seems fine with either OpenVPN or wireguard tunnels. In fact my typical day has me running the wifi-calling tunnel inside a wireguard tunnel that runs inside an OpenVPN tunnel. No problem.
